In cooperation with the U.S. Consumer Product Safety Commission, the Trane Co., a division of American Standard, is voluntarily recalling 9,900 accessory electric heaters. These heaters are used to provide supplemental heat in heat pump or electric heating systems.

Whether in the cooling, fan, heating or off mode, incorrectly routed wires can cause the accessory heater to continually cycle on and off. Excessive heat could catch nearby combustibles on fire.

Trane and American Standard are aware of four reports of heaters continually running. No property damage or injuries were reported.

The auxiliary electric heaters were sold as a component in various models of Trane and American Standard brand air handlers for heating and air conditioning systems. The air handler nameplate provides a list of accessory electric heater model numbers that could be installed in that air handler.

The model numbers for the recalled units are BAYHTR1419A and B.

The model numbers for air handlers that may contain the recalled heater units are: TWG048A140A; TWG060A150A; TWV036B140A; TVF036A140A; TWE030C140A,B; TWE030C140F; TWE030C14FB; TWE036C140A,B; TWE036C140F; TWE036C14FB; TWE042C140B,C; TWE042C14FB,C; TWE048C140A,B; TWE048C140F; TWE048C14FC; TWE060C15FC,D; TWE060D150A,B; TWE030P130A,B; TWE030P13FA,B; TWE036P130A,B; TWE030P13FA,B; TWE042P130A,B; TWE042P13FA,B; TWE048P130A,B; TWE048P13FA,B; TWE060P130A,B; TWE060P13FA,B; TWE063P130A,B; TWE063P13FA,B; TWE031E13FA,B; TWE037E13FA,B; TWE040E13FA,B; TWE065E13FA,B.

All models have a single Arabic digit after this final letter.

Independent installers of Trane and American Standard equipment sold these accessory heaters nationwide from October 1997 through May 1999 for between $250 and $400.

Consumers were warned to remove any combustible material from around the air handlers with recalled heaters.

Consumers with one of these electric heaters were also told to call their local independent Trane or American Standard dealer for a free inspection and repair, if needed. Consumers could also contact Trane at 888/556-0125 between 7 a.m. and 5:30 p.m. CDT Monday through Friday.
